MNT Reform DIY Arm Linux laptop has been in the works at least since 2017. The open source hardware laptop is also fully modular with Boundary Devices Nitrogen8M SoM featuring NXP i.MX 8M quad-core Cortex-A53 processor and 4GB RAM, M.2 NVMe SSD storage, and standard, replaceable 18650 batteries.
The good news is the laptop is now almost ready for prime-time and has been launched on Crowd Supply with price starting at $999 in DIY kit form without storage, and $1,300 for a complete, assembled system with 256GB NVMe storage. If you don’t have that amount of money to spend, but would like to support the project, a $40 MNT Reform T-shirt is also offered. Alternatively, the motherboard only goes for $550.

MNT Reform is the one and only OSHWA certified laptop that I could find (on May 9, 2020), but not the first “open source hardware” laptop running Linux, with for example PineBook Pro which is virtually unbeatable in terms of price ($200) and performance (Rockchip RK3399). However, MNT Reform has a fairly different design philosophy as openness, user serviceability, and modularity were the main goals, even guiding some hardware design decisions that increased the price of the device.
All hardware design files have been released, and the software (Debian 11 installer with Linux 5.x mainline preloaded on MicroSD card) can operate with open-source only components, except for the RAM. Some specific features that you may optionally opt to use do require closed-source binary blobs including HDMI output (HDCP blob). You’ll find hardware (KiCad), 3D design, and software on the MNT Reform website.
The crowdfunding campaign launched less than 24 hours ago, and it’s not going too bad with $60,000 raised out of $115,000 funding target. The prices listed in the introduction include free worldwide shipping, and backers should expect their rewards to ship in December 2020.
